Definitions
- This invention relates to an automatic transmission control device which can change the shift point by means of selecting the damping force of a suspension, thereby improving the drivability.
- FIG. 2 is a block diagram showing the system configuration of conventional automatic transmission control means
- FIG. 3 is a block diagram showing the system configuration of a conventional suspension control device.
- the automatic transmission control means is provided with shift pattern mode selecting means 1 for selecting a shift pattern mode, shift pattern setting means 3 for setting a shift pattern from the mode which is selected by the shift pattern mode selecting means 1, and automatic transmission control means 4 for controlling the shift operation on the basis of the shift pattern which is set by the shift pattern setting means 3.
- the suspension control device is provided with suspension mode selecting means 2 for selecting a damping force of a suspension, and suspension control means 5 for controlling the switching of the damping force in accordance with the suspension mode which is selected by the suspension mode selecting means 2.
- a driver selects the shift pattern by operating the shift pattern mode selecting means 1.
- the shift pattern setting means 3 is provided with shift patterns as shown in FIG. 4 in which shift points are set on the basis of a vehicle speed and a throttle opening. Further, in an economy mode wherein the fuel consumption has priority, the shift point is positioned at a lower speed side, and, in a power mode wherein the driving force and acceleration are given with priority, the shift point is positioned at a higher speed side.
- the shift pattern setting means 3 the shift pattern of the mode which is selected by the shift pattern mode selecting means 1 is set.
- the suspension control device of FIG. 3 controls the automatic transmission on the basis of information such as the vehicle speed, throttle opening and the shift pattern which are set by the shift pattern setting means 3.
- the driver selects the damping force of the suspension by operating the suspension mode selecting means 2.
- the suspension control means 5 controls the suspension so as to switch the damping force.
- the shift pattern used in the automatic transmission control means 4 is exclusively selected by the shift pattern mode selecting means 1, and therefore the shift pattern remains unchanged even when the running conditions are changed and another mode for the suspension is selected. Accordingly, there is a problem in that the shift operation dose not match a desired running condition of the vehicle and hence the vehicle fails to perform in accordance with the desired running condition.
- the invention has been made to obviate the aforementioned, providing an automatic transmission control device which allows a vehicle to operate in accordance with the driver's requirement so as to improve driveability.
- the automatic transmission control device in the present invention comprises shift pattern setting means for setting a shift pattern on the basis of information from shift pattern mode selecting means and suspension selecting means.
- the shift pattern setting means has a variety of shift patterns corresponding to combinations of shift pattern modes and damping force values from the suspension selecting means, respectively, the shift pattern setting means comparing the combinations with a pair of the selected shift pattern mode and the set damping force value to set one of the variety of shift patterns for the shift operation.
- the shift pattern set means sets a shift pattern, on the basis of the selected shift pattern mode for the automatic transmission, which is selected by the shift pattern mode selecting means and the damping force of the suspension, which in turn is selected by the suspension mode selecting means.
- FIG. 1 is a block diagram showing the configuration of an automatic transmission control device which is an embodiment of the invention.
- FIG. 2 is a block diagram showing the system configuration of conventional automatic transmission control means.
- FIG. 3 is a block diagram showing the system configuration of a conventional suspension control device.
- FIG. 4 is a view showing shift patterns used in a conventional automatic transmission control.
- FIG. 1 is a block diagram showing the configuration of an embodiment of the invention.
- the components identical with those in FIGS. 2 and 3 are designated by the same references.
- the control device is provided with shift pattern mode selecting means 1 for selecting a shift pattern mode of an automatic transmission, suspension mode selecting means 2 (as a suspension setting means) for selecting a damping force of a suspension, and shift pattern setting means 3 for setting a shift pattern, on the basis of the selected shift pattern mode which is selected by the shift pattern mode selecting means 1 and also the damping force of the suspension which is selected by the suspension mode selecting means 2.
- shift pattern setting means 3 is a feature of the invention.
- automatic transmission control means 4 controls the shift operation of the automatic transmission on the basis of the shift pattern which is set by the shift pattern setting means 3.
- suspension control means 5 controls the damping force of the suspension in accordance with the selected damping force which is selected by the suspension mode selecting means 2.
- the shift pattern setting means 3 receives data of the shift pattern mode of the automatic transmission which is selected by the shift pattern mode selecting means 1 and also data of the damping force of the suspension which is selected by the suspension mode selection means 2. Thereupon, as shown in Table 1 below, the shift pattern setting means 3 sets the shift pattern, on the basis of a combination of the shift pattern mode which is selected by the shift pattern mode selecting means 1 and the damping force which is selected by the suspension mode selecting means 2, i.e. the selected suspension mode. The shift pattern thus set is input to the automatic transmission control means 4.
- the shift pattern a has a shift point positioned in the side of a lower vehicle speed and gives priority to the fuel consumption.
- the shift pattern b has a shift point positioned in the side of a higher vehicle speed and gives priority to the driving force and acceleration as compared with the shift pattern a.
- the shift pattern c has a shift point positioned in the side of a vehicle speed higher than that of the shift pattern b.
- the shift pattern d has a shift point positioned in the side of a further higher vehicle speed and is most excellent among the four patterns in acceleration and driving force.
- the automatic transmission control means 4 controls the automatic transmission, on the basis of sensor signals indicative of the actual vehicle speed, the actual throttle opening, etc. in accordance with the shift pattern which is set by the shift pattern setting means 3.
- the suspension control means 5 controls the damping force of the suspension in accordance with the damping force value which is selected by the suspension mode selecting means 2.
- the automatic transmission control device is so constructed that the shift pattern setting means sets the shift pattern, on the basis of the shift pattern information for the automatic transmission which is selected by the shift pattern mode selecting means and also on the basis of the damping force information for the suspension which is selected by the suspension mode selecting means, and that the automatic transmission control means controls the shift operation of the automatic transmission on the basis of the shift pattern this set. Therefore, the automatic transmission control device of the invention can achieve the effect that the running characteristics according to the driver's requirement are obtained and the driverbility is improved.
